LED drivers combine normal and emergency lighting modes

June 08, 2016 // By Julien Happich
The EM powerLED 45 W LED Drivers in PRO DIM and SELV versions from Tridonic combine normal and emergency lighting modes for LED luminaires in one unit.

The compact housings of the installation version save space in the luminaire. The combination LED Drivers provide an output of 45W in normal operation, and the integrated battery system produces up to 4W of emergency lighting power. In normal operation EM powerLED PRO DIM 45 W can be dimmed via DALI, switchDIM or the corridorFUNCTION and is prepared for ready2mains. Emergency light functionality is monitored centrally via DALI. One DALI address is sufficient for performing lighting control, dimming and the prescribed emergency lighting tests and for documenting them centrally – for example via connecDIM or the x/e-touchPANEL. The devices are compatible with the EXCITE series of LED Drivers from Tridonic and can be easily integrated in any installation.
 
EM powerLED ST FX 45 W 50 V with SELV qualification is a version with fixed output and integrated self-test function. In normal operation this LED Driver provides the dimming function via the simple corridorFUNCTION and does not require a higher-ranking DALI system. The weekly function tests prescribed for emergency lighting and the annual service life test are performed via the integrated automatic self-test function. A two-colour LED status display indicates the test results.
